<h2>SQLite Release 3.6.0 On 2008 July 16 (3.6.0 beta)</h2><p><ul>
<li>Modifications to the <a href="../c3ref/vfs.html">virtual file system</a> interface
    to support a wider range of embedded systems.
    See <a href="../35to36.html">35to36.html</a> for additional information.
    <font color="red">*** Potentially incompatible change ***</font></li>
<li>All C-preprocessor macros used to control compile-time options
    now begin with the prefix "SQLITE_".  This may require changes to
    applications that compile SQLite using their own makefiles and with
    custom compile-time options, hence we mark this as a
    <font color="red">*** Potentially incompatible change ***</font></li>
<li>The SQLITE_MUTEX_APPDEF compile-time option is no longer supported.
    Alternative mutex implementations can now be added at run-time using
    the <a href="../c3ref/config.html">sqlite3_config()</a> interface with the <a href="../c3ref/c_config_getmalloc.html">SQLITE_CONFIG_MUTEX</a> verb.
    <font color="red">*** Potentially incompatible change ***</font></li>
<li>The handling of IN and NOT IN operators that contain a NULL on their
    right-hand side expression is brought into compliance with the SQL
    standard and with other SQL database engines.  This is a bug fix,
    but as it has the potential to break legacy applications that depend
    on the older buggy behavior, we mark that as a
    <font color="red">*** Potentially incompatible change ***</font></li>
<li>The result column names generated for compound subqueries have been 
    simplified to show only the name of the column of the original table and
    omit the table name.  This makes SQLite operate more like other SQL
    database engines.</li>
<li>Added the <a href="../c3ref/config.html">sqlite3_config()</a> interface for doing run-time configuration
    of the entire SQLite library.</li>
<li>Added the <a href="../c3ref/status.html">sqlite3_status()</a> interface used for querying run-time status
    information about the overall SQLite library and its subsystems.</li>
<li>Added the <a href="../c3ref/initialize.html">sqlite3_initialize()</a> and <a href="../c3ref/initialize.html">sqlite3_shutdown()</a> interfaces.</li>
<li>The <a href="../c3ref/c_open_autoproxy.html">SQLITE_OPEN_NOMUTEX</a> option was added to <a href="../c3ref/open.html">sqlite3_open_v2()</a>.</li>
<li>Added the <a href="../pragma.html#pragma_page_count">PRAGMA page_count</a> command.</li>
<li>Added the <a href="../c3ref/next_stmt.html">sqlite3_next_stmt()</a> interface.</li>
<li>Added a new <a href="../rtree.html">R*Tree virtual table</a></li>
</ul></p>

      in a single page is also available.  A detailed history of every
